Just been putting a roof on my workshop using corrugated steel sheets. It's gone on ok - a lot bendier that I thought it'd be, the roofline has a bit of an undulation where some of my fixings are tighter than others, but I think I can even it out.
I'm not sure what to do at the apex. I decided not to buy the l-shaped flashings to finish it, there's a corrugated chapel not far from us that has lovely timber bargeboards and with a spike at the top, that's what I'm trying to do. However, the metal on the chapel seems to cover the top of the bargeboard and the join between the two is perfect, layers of paint & putty over 100 years have probably sealed it. My metal is flapping around with a noticeable gap.
My plan now is to find some waterproof foam pipe insulation and tuck it into the corrugation so it has some support. Then screw through the metal into the top edge of the barge board. Not very elegant, & I'm not 100% certain this'll work, so just having a 24 hour think about it before I dive in. Any better ideas anyone?
